Looking to Move from Unraid

  • I am looking to move from unraid to OMV. So i can snapraid and zfs.

    Right i now i have 10disk array in unraid with 2 disk for parity.

    The disks are xfs formatted. What is the best way to move the over to snapraid in omv without losing data?

    I will be using seperate zfs array for critical data

  • snapraid works on top of existing filesystems. So, if they are xfs, you would just need to move data off two disks (if you want two parity disks) and just start using it. No data loss.

  • I am in an almost identical situation, so maybe we can kill two birds with one stone? I am moving from UnRAID to OMV, have a 12 bay SuperMicro chassis with two parity disks, but what is slightly different is that I am using two Mellanox ConnectX-2 10Gb vards to create a 10 gig P2P link to transfer approximately 24TB worth of data and seed the OMV (which will start off being a backup NAS, but which I want to convert to my main NAS afterward). I then intend to use an RSync script to create/maintain incremental backups.


    Is there a tutorial regarding transferring the data? It would seem to be the one difference in our two scenarios.

    I have 6 4tb disks that i could use to transfer the data...but i need about 65tb to be able to transfer

  • Then maybe I was a bit premature in saying our scenarios were similar! I have - totalled it up - 29TB of data, and 2 x 4TB 3.5 inch SATA drives, 72 x 4 TB 3.5 inch SAS drives, 72 x 1 TB SATA drives and probably 20+ miscellaneous SSDs of between 100GB and 1 TB which I could use. I have one 12 bay UnRAID NAS, 2 other Supermicro 12 bay chassis, 3 Dell R720xd chassis (each with 24 2.5 inch bays), one SuperMicro 16 bay chassis and one SuperMicro 24 bay chassis. I want to build a server in one of the 12 bay chassis (housing 12 x 4 TB drives) with a 12 bay disk shelf attached at a later date, and transfer the files across with as little trouble (and as little time) as possible.

  • I run a third party snapRAID script that does a diff, sync, and scrub on cron every fourth day at 3:00am. It takes just under three hours to run.

  • Do you mind sharing the script?

    Thanks in advance

    This one here:


    Code
    https://gist.github.com/mtompkins/91cf0b8be36064c237da3f39ff5cc49d

    It needs a minor change though. Comment out the wait statements with a # on lines: 145,194,207,229,249,313,370,382, and 401.


    There are other similar scripts out there.

  • I am willing to take up that and AD integration plugin...I write java and groovy code for Job .Is there a documentation how to start plugin development?

    There isn't much up to date docs. This is the most recent plugin guide - https://github.com/skyajal/diypluginguide3.x. The best suggestion I have is looking at the source code for OMV and the plugins and ask questions. I will try to answer anything you ask.

    This AD plugin is super old and not finished. Not sure if it will help
